+## [1.1.0] - 2026-01-11
+
+### 🏗️ Major Refactoring Release
+
+Complete architectural overhaul for better maintainability and performance.
+
+### Changed
+
+#### Modular Architecture
+- **Refactored from single file to multi-module structure**
+  - From: `memory.rs` (2505 lines, monolithic)
+  - To: 35+ files in 8 organized modules
+- **New module structure:**
+  - `src/types/` - Core data models (Entity, Relation, KnowledgeGraph)
+  - `src/protocol/` - JSON-RPC and MCP protocol handling
+  - `src/knowledge_base/` - Core engine with CRUD, queries, temporal
+  - `src/tools/` - 15 MCP tools organized by category (memory, query, temporal)
+  - `src/search/` - Semantic search with synonym expansion
+  - `src/server/` - MCP server implementation
+  - `src/validation/` - Entity and relation type validation
+  - `src/utils/` - Timestamp and user utilities
+- **Library + Binary separation**
+  - `src/lib.rs` - Public API for embedding
+  - `src/main.rs` - Minimal binary entry point
+
+#### Performance Optimization
+- **Mutex → RwLock migration** for `KnowledgeBase.graph`
+  - Allows multiple concurrent readers (60% of operations are reads)
+  - Write operations still have exclusive access
+  - Significant performance boost for multi-agent scenarios
+- **Documentation:** See `docs/Proposed-RwLock.md` for risk analysis
+
+#### Docker
+- Updated `Dockerfile` for new `src/` directory structure
+- Better layer caching with separate Cargo.toml and src copies
+
+### Added
+- `src/lib.rs` - Library crate for embedding in other projects
+- `tests/integration_tests.rs` - 8 integration tests including concurrency tests
+- `docs/Proposed-RwLock.md` - RwLock migration documentation
+
+### Technical Details
+- **Test suite expanded:** 16 tests (7 unit + 8 integration + 1 doc)
+- **Zero-cost abstractions:** No runtime overhead from modularization
+- **Backward compatible:** All 15 MCP tools unchanged
+
